You can pick out a Seamaster Diver 300M from across a room, and it's the waves that do it. Omega laser-engraves them into a polished blue ceramic dial, then adds skeleton sword hands, a double marker at 12 and a date at 6, inside a blue ceramic bezel with a scalloped edge. On the left of the case, at 10 o'clock, sits a helium escape valve. Omega's own page says the valve is for professional use in pressure chambers, so you'll probably never need it, but it's part of the look. The steel case is 42 mm across and 13.56 mm thick, it's water resistant to 300 metres, and inside is Omega's automatic calibre 8800. In the US it lists at $6,700.
The Submariner Date in our other dive watch guide has round and baton markers and Mercedes hands on a plain black dial, so the picks there won't do here. The Seamaster's face is the waves, the hands and the double marker, and that's what we looked for first. We went through watches like the Omega Seamaster on sale in the US today and kept six that look like it, from $190 to $4,550. All six have a blue dial and a blue bezel, and five of them have waves. Each one comes with what it gets wrong. Prices are regular US list prices from the brands' own US sites, not sale prices, checked on 25 October 2026. The photos are to scale, so if a watch looks smaller here, it is. The one exception is the Pagani, whose only photo is taken from an angle, so its size is approximate.
One of the six, the Pagani, is a Seamaster homage: the watch world's word for a watch that follows a famous design on purpose, under its own name. Retailers often sell for less than the list prices here. Where we couldn't confirm that Amazon lists the exact watch, its Amazon button runs a search instead.
This is the watch every pick is measured against, the Seamaster Diver 300M, reference 210.30.42.20.03.001:
Nothing below has all of it. Only the Pagani copies the skeleton hands, the double marker and the scalloped bezel together. The Seiko has the double marker but not the rest, and only the Tissot Seastar 2000 lists a helium escape valve. Every pick but the Tissot Seastar 1000 has waves on the dial. Above $5,000 you're close to paying for the Omega itself, and nothing we found there looked enough like it to make the list.
| Watch | US list price | Case | Dial | Water resistance |
|---|---|---|---|---|
| Pagani Design PD-1685 (homage) | $190 | 42 mm | Blue, waves | 200 m |
| Tissot Seastar 1000 Powermatic 80 | $925 | 43 mm | Blue, plain | 300 m |
| Tissot Seastar 2000 Professional | $1,050 | 44 mm | Blue gradient, waves | 600 m |
| Seiko Prospex SPB483J1 | $1,100 | 41.3 mm | Teal blue, waves | 300 m |
| Mido Ocean Star 200C | $1,360 | 42.5 mm | Blue, waves | 200 m |
| TAG Heuer Aquaracer Professional 300 | $4,550 | 42 mm | Blue, waves | 300 m |
| Omega Seamaster Diver 300M, for comparison | $6,700 | 42 mm | Blue, waves | 300 m |
Nothing here copies more of the Seamaster's face, and nothing costs less. The navy dial has the waves, the skeleton sword hands, the double marker at 12 and the date at 6, inside a blue bezel with a scalloped edge, on a steel bracelet. The 316L steel case is 42 mm across, the same as the Omega's, and 14 mm thick, with a screw-down crown and an anti-reflective sapphire crystal. It's water resistant to 200 metres, and inside is a Miyota 8215 automatic with 42 hours of power reserve. Order the variant Pagani calls "Full Blue / Steel". The one it calls "Blue / Steel" has a white dial.
What you give up: the dial says Pagani Design, there's no helium escape valve, and it's rated to 200 metres against the Omega's 300. The case is 0.44 mm thicker and the power reserve is 42 hours against 55. Pagani doesn't publish the lug-to-lug length or say what the bezel is made of, and its only photo of this variant is taken from an angle. It costs $190, a thirty-fifth of the Omega.
This is where we'd send most people with a budget under $1,000. It's the cheapest watch here rated to 300 metres, like the Omega, and it has a blue ceramic bezel ring, a sapphire crystal and the date at 6, on a steel bracelet. Inside is Tissot's Swiss automatic Powermatic 80, with 80 hours of power reserve, 25 more than the Omega. The steel case is 43 mm across and 12.7 mm thick, a millimetre wider and a little thinner than the Omega's, and Tissot's US store had it in stock.
What you give up is the waves. The blue dial is plain, the hands are plain swords, and there's a single triangle at 12 rather than the double marker. There's no helium escape valve, the crystal's anti-reflective coating is on the underside only, and Tissot doesn't publish the lug-to-lug length. It costs $925, about a seventh of the Omega.
Pick this one if the waves and the valve matter more to you than the bracelet. Tissot calls the dial blue gradient, and its photo shows a wave pattern across it, under a blue ceramic bezel ring with the date at 6. The case has a helium escape valve, the only pick here that lists one, and it's water resistant to 600 metres, twice the Omega's rating, under a sapphire crystal. Inside is the Powermatic 80 again, with 80 hours of power reserve. The steel case is 44 mm across and 15.29 mm thick.
What you give up is the steel bracelet. In blue, the Seastar 2000 comes only on a blue rubber strap, and the 44 mm bracelet version we found has a black dial. The case is 2 mm wider and about 1.7 mm thicker than the Omega's, the hands are plain swords, and there's a triangle at 12 rather than the double marker. Tissot doesn't publish the lug-to-lug length or say where the valve sits. It costs $1,050, about a sixth of the Omega.
Seiko went its own way with this one, and it's still the only pick besides the Pagani with the Seamaster's double marker at 12. Seiko says the dial pattern is inspired by waves, and in its photo the blue leans toward teal. The steel case is 41.3 mm across, 12.5 mm thick and 48.2 mm from lug to lug, a little smaller than the Omega in every direction, under a sapphire crystal, with a blue bezel that turns one way. It's water resistant to 300 metres, like the Omega, and inside is Seiko's 6R55 automatic, with about 72 hours of power reserve.
You lose the round shape. Seiko calls the bezel polygonal, and the case follows it. The hands are faceted rather than skeleton, the date sits between 4 and 5 rather than at 6, and there's no helium escape valve. Seiko doesn't say what the bezel is made of. Its US page lists the watch at $1,100, a sixth of the Omega, but sends you to a store locator rather than a cart.
If you want the waves, a blue ceramic bezel and a steel bracelet from a Swiss brand, this is the one we'd look at first, because it's the cheapest way we found to have all three. The navy dial is patterned with waves, and the hour and minute hands are open near the centre, a little like the Omega's skeleton hands. The ceramic bezel turns one way. The 316L steel case is 42.5 mm across and 12.3 mm thick, under a sapphire crystal that's anti-reflective on both sides, and it's water resistant to 200 metres. Inside is Mido's Caliber 80 automatic, with up to 80 hours of power reserve.
What you give up: the day and the date sit side by side at 3, where the Omega has a date alone at 6. The markers are round dots with a triangle at 12 rather than the double marker, it's rated to 200 metres against 300, and there's no helium escape valve. It costs $1,360 in Mido's US store, a fifth of the Omega.
This is the best-built watch here, and the dearest. TAG Heuer calls the dial a "blue wavy pattern dial", and it sits under a blue ceramic bezel with the date at 6, on a three-link steel bracelet. The steel case is 42 mm across, the same as the Omega's, and 12 mm thick, and it's water resistant to 300 metres. Inside is TAG Heuer's TH31-00 automatic, certified as a chronometer, with 80 hours of power reserve. TAG Heuer's page doesn't list the crystal, and Exquisite Timepieces, an authorized dealer, gives it as sapphire.
You give up the round bezel and the Omega's hands. The bezel has twelve sides, the hands are faceted swords, the seconds hand is orange, and there's a single marker at 12. There's no helium escape valve, and TAG Heuer doesn't publish the lug-to-lug length. It costs $4,550, two thirds of the Omega's price, which is a lot to pay for a different watch.
